Bsc Preferred VHB491012R Vhb Tape Clear Acrylic Adhesive

Product Description

The BSC PREFERRED VHB491012R is a very high bond (VHB) tape designed to replace mechanical fasteners such as rivets, bolts, screws, spot-welds, and liquid adhesives in demanding structural and sealing applications. The tape features a clear acrylic foam core with an acrylic adhesive and ships with a red polyethylene film liner for easy handling. It handles an operating temperature range of -40 degrees F to 200 degrees F and resists moisture, solvents, and UV exposure. Licensed tradespeople and experienced installers in glazing, signage, and construction rely on this tape for permanent, load-bearing bonds that remain stable across wide temperature swings.

This tape is well suited for sealing skylight inner and outer domes, mounting back-lit translucent signs, and edge-bonding resin-filled glass panels. Its clear, colorless formulation makes it a strong fit for glass and acrylic substrates where a visible fastener or colored adhesive would be unacceptable. Typical applications include commercial glazing assemblies, architectural signage, and transparent panel installations where a clean, hidden bond line is required.

Key Features

• Replaces rivets, bolts, screws, spot-welds, and liquid adhesives in many permanent fastening scenarios
• Clear acrylic foam core with acrylic adhesive - suitable for colorless or transparent bond lines
• Operating temperature range: -40 degrees F to 200 degrees F
• Resistant to moisture, solvents, and UV radiation for long-term outdoor and indoor durability
• Red polyethylene film liner for precise tape placement and clean removal before bonding
• Recommended for glass and acrylic substrates; also suited for skylight dome sealing and sign mounting

Compatibility

Designed for use on glass and acrylic surfaces; suitable for skylight inner and outer dome sealing, back-lit translucent sign mounting, and resin-filled glass edge-bonding applications.

Installation Notes

Surface preparation is critical for maximum bond strength - clean all substrates thoroughly with an appropriate solvent cleaner and allow to dry completely before applying the tape. Remove the red polyethylene liner just before application and apply firm, even pressure across the full tape surface to ensure full contact. Allow adequate dwell time at room temperature before subjecting the bond to load or stress. This product is intended for installation by qualified tradespeople or experienced fabricators familiar with structural adhesive tape applications.
